In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figures 1 to 15 As shown, a feed port 2, a material transfer mechanism 3, a turntable mechanism 4, a mobile weighing mechanism 5, a flip cover assembly 6, a cover pressing assembly 7, a dust removal mechanism 8 and an electric control system 9 are arranged on a frame 1, and an automatic transmission mechanism is arranged on the outside of the frame 1; the inner side of the material transfer mechanism 3 is connected to one end of the turntable mechanism 4, and the other end of the turntable mechanism 4 is sequentially provided with a flip cover assembly 6, a mobile weighing mechanism 5, a dust removal mechanism 8 and a cover pressing assembly 7, and a plurality of groups of barrel clamps 10 facing outward are evenly arranged along the circumference of the turntable mechanism 4, and the barrel clamps 10 are opposite to the feed port 2, and the material transfer mechanism 3 is used to push the sample collection barrel 11 back and forth between the barrel clamps 10 and the automatic transmission mechanism. Specifically, the barrel clamp 10 includes a clamp block 71, a long bolt 72 and a rubber wheel 73, the clamp block 71 is provided with an arc opening facing outward, and two interval-stacked clamp blocks 71 are fixedly connected to the turntable body 39 through a plurality of groups of long bolts 72, and a rubber wheel 73 is sandwiched between the two sides of the clamp block 71.

[0038] like Figure 4 and Figure 5As shown, the material moving mechanism 3 includes a material moving mounting plate 12, a material pushing motor 13, a material pushing screw 14, a T-nut 15, a connecting plate 16, a connecting bearing 17, a first light rod 18, a square tube 19, a barrel pushing frame 20, a first buffer block 21, a sealing plate 22 and a stroke sensing seat 23. The material moving mounting plate 12 is relatively fixed on the frame 1, and two in-position sensors 74 are fixed at one end of the outer material moving mounting plate 12, and a material pushing motor 13 is fixed at the other end. The output end of the material pushing motor 13 is transmission-connected to one end of the material pushing screw 14 through a transmission gear, and the other end of the material pushing screw 14 is fixedly connected to the material moving mounting plate 12; the material pushing screw 14 is connected to the material moving mounting plate 12 through a T-nut. The nut 15 is connected to the middle part of the connecting plate 16, and connecting bearings 17 are fixed on both sides of the upper end of the connecting plate 16. A first light rod 18 is inserted into the connecting bearing 17, and both ends of the first light rod 18 are respectively fixed on the relatively arranged material transfer mounting plate 12; the middle part of the lower end of the connecting plate 16 is fixedly connected to the barrel pushing rack 20 through a square tube 19, and first buffer blocks 21 are respectively provided on the inner and outer sides of the lower end of the barrel pushing rack 20, and there is a height misalignment between the first buffer blocks 21 on both sides. The first buffer blocks 21 of different heights on both sides clamp the two sides of the sample collecting barrel 11, so that the material transfer mechanism 3 can clamp the sample collecting barrel 11 more stably when pushing the sample collecting barrel 11 while positioning the sample collecting barrel 11.

[0039] A sealing plate 22 is fixedly arranged on the outer side of the barrel pusher 20; a travel sensing seat 23 is also installed between the material transfer mounting plates 12, and a first travel sensor 24 is arranged on the travel sensing seat 23. The two first travel sensors 24 are used to sense whether the sample collection barrel 11 is in place when it is out of the barrel or in the barrel. The material transfer mechanism 3 is smooth and stable during the movement and occupies little space.

[0040] The working process of the material transfer mechanism 3 is as follows: after the barrel clamp 10 is positioned at the barrel outlet position and the sample barrel position, the material transfer mechanism 3 starts to operate, the material pusher motor 13 works, the first buffer block 21 clamps the sample barrel 11 filled with coal samples, and pushes the sample barrel 11 filled with coal samples through the sample barrel position to the unpowered roller conveyor 60 for transportation. The material pusher motor 13 is not retracted. While the unpowered roller conveyor 60 transports the sample barrel 11 filled with coal samples out, the empty sample barrel 11 is transported by the powered roller conveyor. The conveyor 59 transfers from left to right to the material transfer mechanism 3. After the arrival sensor 74 senses the empty sample collecting barrel 11, the card reading program is started, the RFID chip is verified and the chip TID is recorded, and the pushing motor 13 is retracted. The empty barrel is smoothly pushed back into the idle barrel clamp 10 under the action of the buffer block and the sealing plate 22. The sample collecting barrel 11 is pushed in this cycle. After the sample collecting barrel 11 enters the turntable mechanism 4, it is transferred to the mobile weighing mechanism 5, and the barrel weighing is started and the tare weight of the empty barrel is recorded.

[0041] like Figure 8 and Fig. 9As shown, the mobile weighing mechanism 5 includes a groove-type mounting seat 25, a first electric push rod 26, a weighing support plate 27, a linear bearing 28, a second light rod 29, a hopper 30, a material blocking plate 31, a first weighing sensor 32, an arc door 33, a pressure plate 34, a deep groove ball bearing 35, a sealing plate 36 and a second stroke sensor 37. The groove-type mounting seat 25 is fixedly mounted on the frame 1, and the first electric push rod 26 is passed through the middle of the groove-type mounting seat 25. The first electric push rod 26 is fixedly connected to the weighing support plate 27. Linear bearings 28 are fixed on both sides of the upper end of the weighing support plate 27. A second light rod 29 is passed through the linear bearing 28. Both ends of the second light rod 29 are fixed On the groove-type mounting seat 25; a hopper 30 is fixedly penetrated on the weighing support plate 27, a baffle plate 31 is provided on one side of the upper end of the hopper 30, and two opposite first weighing sensors 32 are also provided on the hopper 30, and the height of the first weighing sensor 32 is lower than the height of the baffle plate 31, arc doors 33 are provided on both sides of the lower end of the hopper 30, and a pressure plate 34 is connected between the arc doors 33, and a deep groove ball bearing 35 is provided at the lower end of the pressure plate 34; a sealing plate 36 is provided at the lower end of the baffle plate 31; two second stroke sensors 37 are also provided on the weighing support plate 27, and the second stroke sensor 37 is arranged between the hopper 30 and the second light rod 29, and is used to sense the position of the hopper 30.

[0042] The top of the hopper 30 can be vertically opposite to the feed port 2, and the opening of the feed port is larger than the opening of the feed port 2, so that it is convenient to receive all incoming materials.

[0043] The setting of the two first weighing sensors 32 makes the weighing weight of the raw coal sample put into the feed port 2 more accurate, providing more accurate weight information for subsequent processing actions. While weighing, the flip cover assembly 6 has completed the action to open the barrel cover 66 of the sample collecting barrel 11, and the electric push rod retracts. When it is detected by the sensor on the scale support plate 27, the electric push rod stops moving. At this time, the lower end of the hopper 30 also opens the drop port synchronously and stops accurately above the sample collecting barrel 11 for dropping.

[0044] The setting of the mobile weighing mechanism 5 enhances the weighing capacity of the hopper 30 and makes the translation of the hopper 30 smoother. The thrust point of the first electric push rod 26 is installed in the middle of the two second light rods 29 to make the movement of the hopper 30 more uniform and stable.

[0045] like Figure 6 and Figure 7As shown, the turntable mechanism 4 includes a rotating motor 38, a turntable body 39, a rotating support 40, a rotating bearing 41, a spindle 42, an eyebolt 43 and a sensor mounting plate 44. The frame 1 is fixedly provided with a rotating motor 38, the output end of the rotating motor 38 is meshed with the turntable body 39 for transmission, the bottom of the turntable body 39 is coaxially fixed with a rotating support 40, the center of the rotating support 40 is rotatably connected to the spindle 42 through the rotating bearing 41, and the lower end of the spindle 42 is fixedly connected to the frame 1; the center of the upper end of the turntable body 39 is fixed with an eyebolt 43; the turntable body 39 is evenly opened along the circumferential direction. There are multiple groups of square through holes, and barrel clamps 10 are provided around the square through holes. A sensor mounting plate 44 is fixedly provided on the inner side of one of the barrel clamps 10. A sample barrel in-situ sensor is installed on the sensor mounting plate 44, which is used to sense the return to the initial position after the turntable body 39 is reset. The initial position is opposite to the material shifting mechanism 3; a counting sensor is installed at the connection between the rotating motor 38 and the turntable body 39, which is used to detect the number of teeth on the outer ring of the turntable to ensure that the sample collecting barrel 11 stops at the correct position; the two sensors on the turntable mechanism 4 are not shown in the attached figure, which are conventional sensors that can be purchased on the market.

[0046] like Fig.10 As shown, the flip cover assembly 6 includes a flip cover mounting plate 45, a second electric push rod 46, a locking ring 47, a crank connecting rod 48, a flip cover arm 49, a magnetic lock 50 and a second buffer block 51. The flip cover mounting plate 45 is fixedly provided on the frame 1, and the second electric push rod 46 is provided on the flip cover mounting plate 45. The output end of the second electric push rod 46 is transmission-connected with the crank connecting rod 48 through the locking ring 47. One end of the crank connecting rod 48 is fixedly connected with the flip cover arm 49. A flip cover arm 49 is installed on the flip cover arm 49, and one end of the flip cover arm 49 is provided with a magnetic lock 50. The second buffer blocks 51 are respectively provided on both sides of the lower end of the flip cover mounting plate 45, and the distance between the second buffer blocks 51 is greater than the length of the crank connecting rod 48. The flip cover assembly 6 as a whole is composed of detachable parts and components, which are easy to install, disassemble and replace. In this embodiment, the first electric push rod 26 and the second electric push rod 46 are both dustproof and waterproof, which can effectively reduce the occurrence of malfunctions. The second buffer block 51 effectively reduces the impact of the crank connecting rod 48 on the sample collecting barrel 11 when opening and closing the cover.

[0047] The magnetic lock 50 approaches the combination lock 65, and after the sample collecting barrel 11 is automatically unlocked, the second electric push rod 46 extends out, and the crank connecting rod 48 allows the flip arm 49 to move downward and energize the magnetic lock 50, so that the magnetic lock 50 falls on the barrel cover 66 of the sample collecting barrel 11, and then the second electric push rod 46 retracts. At this time, the barrel cover 66 is opened, waiting for the hopper 30 to drop materials. When the hopper 30 has completed dropping materials and is sensed by the second stroke sensor 37, the flip cover assembly 6 runs again to close the opened barrel cover 66.

[0048] like Fig.13As shown, the dust removal mechanism 8 includes a dust removal mounting seat 52, a dust removal bucket 53, a shutter 54, an inspection window 55, a dust suction pipe 56, a blower 57 and a dust suction box 58. The inner side of the frame 1 is fixedly connected to the dust removal bucket 53 through the dust removal mounting seat 52, and a shutter 54 and an inspection window 55 are provided on one side of the dust removal bucket 53; the upper end of the dust removal bucket 53 is connected to the blower 57 through the dust suction pipe 56, the blower 57 is fixedly mounted on the frame 1, and the output end of the blower 57 is adaptably connected to the dust suction box 58.

[0049] When the coal powder is blown into the dust removal barrel 53, it will not float in the air, effectively preventing a large amount of coal ash from appearing during the working process. It will then pass through the partition in the dust removal barrel 53 and then be discharged through a shutter 54 with a layer of dust-proof isolation cotton. A water tank is provided in the dust removal barrel 53, and the changes in the water in the water tank can be intuitively seen through the inspection window 55. The above can facilitate the staff to operate conveniently during the maintenance of the equipment.

[0050] The automatic transmission mechanism includes a powered roller conveyor 59, an unpowered roller conveyor 60, a transmission motor 61 and a second weighing sensor 62. The outside of the frame 1 is provided with a connected powered roller conveyor 59 and an unpowered roller conveyor 60. The powered roller conveyor 59 is driven to rotate by the transmission motor 61. One end of the powered roller conveyor 59 is opposite to the sealing plate 22 and a second weighing sensor 62 is provided at the lower end. Two in-position sensors 74 are fixedly provided at one end of the material transfer mounting plate 12 for sensing whether the sample collecting barrel 11 has reached the sealing plate 22 of the material transfer mechanism 3. The second weighing sensor 62 weighs the sample collecting barrel 11.

[0051] like Fig.14 As shown, the sample collecting barrel 11 includes a barrel body 63, a clamping member 64, a combination lock 65 and a barrel cover 66. The barrel body 63 is provided with clamping members 64 at the front and rear sides. The clamping members 64 are engaged with the rubber wheels 73. The height of the barrel body 63 can prevent the sample collecting barrel 11 from deflecting and tipping over during the rotation of the turntable body 39.

[0052] A handle 67 is provided above the clamping member 64 to facilitate manual taking;

[0053] The left and right sides of the barrel body 63 are respectively connected to the barrel cover 66 through a password lock 65 and a hinge; the opening width of the barrel body 63 is larger than the width of the feed port 2 to achieve better reception of coal samples; the bottom width of the barrel body 63 is larger than the width of the square through hole to prevent the barrel body 63 from falling.

[0054] In this embodiment, the barrel body 63 and the barrel cover 66 are made of stainless steel, which is reusable and durable. The sample collection barrel 11 is encapsulated with a password lock 65. The electronic password of the password lock 65 is randomly set by the program in the electronic control system 9, which can eliminate human factors and ensure the confidentiality of the sample. The method of attaching an RFID chip (not shown in the figure) on the barrel body 63 and reading it is a common chip reading method in the prior art. The present invention does not make any improvements to the RFID chip and the reading method, so it is not described in detail.

[0055] The gland assembly 7 includes a gland support 68, a tendon plate 69 and a gland block 70. The frame 1 is fixed with a gland support 68. The tendon plate 69 is fixedly attached to one side of the lower end of the gland support 68. The lower end of the tendon plate 69 is a chamfered surface, which provides a certain buffering force to the unclosed barrel cover 66 to avoid direct collision. A gland block 70 is provided on one side of the tendon plate 69, and the gland block 70 is adapted to be connected to the gland support 68 through an adjusting bolt.

[0056] A position sensor is mounted on the sensor mounting plate 44 for sensing the rotational position of each barrel clamp 10 so as to determine the moving position of the barrel clamp 10. The position sensor is not shown in the accompanying drawings and is a common position sensor on the market. The present invention does not make any improvements thereto, so it is not described in detail.

[0057] It needs to be explained that the electronic control system 9 is electrically connected to the motors, sensors and other devices in the material transfer mechanism 3, the turntable mechanism 4, the mobile weighing mechanism 5, the flip cover assembly 6, the pressure cover assembly 7 and the dust removal mechanism 8, respectively. The motors, sensors and the like are all common models on the market that can be purchased by themselves, and the control connection method is also easily implemented by the staff in this field in the prior art. It is not the innovation of the present invention, so the specific control connection method is not marked in the figure and is not described in detail.

[0058] The working process of the present invention is as follows: the empty sample collecting barrel 11 is conveyed from left to right on the powered roller conveyor 59, the in-place sensor 74 senses whether the sample collecting barrel 11 is transferred to the corresponding place of the material transfer mechanism 3, the second weighing sensor 62 weighs the empty sample collecting barrel 11, and at the same time, the turntable mechanism 4 and the material transfer mechanism 3 cooperate with each other to position the barrel clamp 10, and the two first stroke sensors 24 are used to sense whether the material transfer mechanism 3 has the sample collecting barrel 11 in place or in place, and the barrel pusher 20 is provided with a card reader (not shown in the figure), which is a common device on the market to start the card reading program, verify the RFID chip of this sample collecting barrel 11 and record the chip TID;

[0059] The sample collecting barrel 11 is pushed into the positioned barrel clamp 10 by the material transfer mechanism 3, and the turntable mechanism 4 rotates, driving the sample collecting barrel 11 to rotate to the flip cover assembly 6, and the sample collecting barrel 11 is opened, and the raw coal sample falls into the sample collecting barrel 11 from the feed port 2 to the hopper 30. At the same time, the dust removal mechanism 8 works to absorb the coal ash generated during the material dropping process. After the material dropping is completed, the flip cover assembly 6 reversely covers the barrel cover 66, and the first weighing sensor 32 weighs and records the raw coal sample falling into the sample collecting barrel 11;

[0060] After the sample is loaded, the sample collecting barrel 11 continues to rotate to the capping assembly 7 to check whether the barrel cover 66 is pressed tightly;

[0061] The capping assembly 7 checks the barrel cover 66 after being pressed, and the sample barrel 11 continues to rotate to the material transfer mechanism 3, and is transported by the material transfer mechanism 3 to the powered roller conveyor 59. The second weighing sensor 62 weighs the sample barrel 11 after the sample is loaded and pressed. At the same time, the left side of the powered roller conveyor 59 starts to transmit the next empty sample barrel 11, and the material transfer mechanism 3 is ready to receive the next empty sample barrel 11. The in-place sensor 74 senses that a sample barrel 11 is sent out, and the powered roller conveyor 59 transports the sample barrel 11 after the sample is loaded and pressed to the unpowered roller conveyor 60. The unpowered roller conveyor 60 transports the packaged sample barrels 11 to the designated collection location.

[0062] The present invention adopts a modular design and has a compact overall structure. It is suitable for use with various sampling machines. The collected samples fall into the feed port 2, and the various components cooperate to achieve automatic sampling and packaging of coal samples. After each sample collection is completed, the lid of the sample collection barrel is automatically closed to ensure that the moisture of the coal sample is not lost. It is unmanned, efficient and environmentally friendly, and is suitable for sampling and packaging of materials in many industries.

[0063] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
